The performance-proved RUBBERTECH heat resistant belt meets hot serviceapplication like hot sintered ore, hot pellet, hotclinker, hot chemical, fertilizer and hot cement etc.RUBBERTECH heat resistant conveyorbelts are most suitable for heat resistant applications where the temperature of material to be carried is over 60。。C(140。。F).
Special Features
•Excellent heat resistant and abrasion resistant cover rubber compound.
•Recommended to protect conveyor belt from surface crackingand hardening by heat
•Specially heat-treated and dipped fabric to minimize carcass shrinkage by heat ageing.
Characteristics indispensably required forheat resistant conveyor belt are as follows
•Rubber cover and carcass should not deteriorate due to heat.
•Rubber cover and carcass should maintain excellent properties, even at high temperatures.
•Rubber cover and carcass should maintain good adhesion to form one unit even when they are exposed to high temperatures
Special Features of Each Grade

This grade belt is highly resistant to variety of heat applications and good service for iron ore, pellets, casting sand, coke and limestone etc. | 50℃ (122℉) Ⅰ 100℃ (212℉) | SBR |
| HT-550 | HT-550 grade is llR(butyl rubber)hot belt compound features excellent heat resistance which is designed to carry hot loads materials with non-cracking property. This belt is most suitable for the materials such as cement products, limestone, clay, slag, etc. | 100℃ (212℉) Ⅰ 130℃ (266℉) | llR |
| HT-710
HT-850 | HT-710 850 grade are the highest quality conveyor belt available to maximum heat resistance. Cover rubbleer is specially formulated EPR(ethylene propylene rubber) to provide extreme heat resistance and ply adhesion for the applications to handle hot cement, clinker, phosphate, hot sintered ore and hot chemical, fertilizer, etc. | 120℃ (248℉) Ⅰ 180℃ (356℉) | EPR (EPDM) |
The surface temperature of heat resistant conveyor belt varies with the material type, belt speed, loadingrate and size depending on circumstance condition.
In order to select the proper heat resistant conveyorbelt, it is necessary to consider not only the materialtemperature to be conveyed but also the surfacetemperature of conveyor belt.
RUBBERTECH HT-710 &HT-850 conveyorbelt is the bestselection for wideranges of hightemperatureapplication.
HT-710 & HT-850conveyor belt isrecommendedfor use hightemperature andwhere high wearresistance isrequired

User of attention
The temperature of material being transported and the belt's surface temperature vary according to the material and shape. For instance, when materials have a temperature of 150℃(300℉) (such as coke or sintered ore) and have a relatively small contact area with conveyor belt's surface temperature remains at 60~80℃(140~180℉). In contrast when powdered material like cement is being conveyed, the material temperature and the belt surface temperature do not differ so greatly. The lifetime of heat resistant belt is largely affected by belt's surface temperature during operation.
Restrictions on the use of heat-resistant belt
SBR Heat-resistant belt
Do not use SBR heat resistant belt when :
•Powdered material is over 70℃(160℉)
•Strong acid or alkaline is used
•Oil products and oil-stained substances are used.
•The operation site or the materials require flame-resistant belts.
EPR(EPDM) Heat-resistant belt
Do not use EPR(EPDM) heat-resistant belts when :
•Powdered material is over 180℃(350℉)
•Oil products and oil-stain other than vegetable oil are present.
•The location of the materials requires flame-resistant belts.
